A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Where does noise really come from? (alien.top)

I know, I know, it can be caused by various factors, like high ISO, poor lighting conditions, long exposure time, heat. (not that I know why the last two cause noise)

But where does noise REALLY come from? What is noise? What does it have to do with photons and photosites?

Noise is just miniscule variations caused by myriad of factors - heat, humidity, different amount of photons, properties of different electronic components, natural backround radiation etc. etc. etc...

And no.... high ISO doesn't cause noise, it just amplifies it.
